HOW TO: DC Jack as 901 Fitting

**nicowolf** · 04-26-2009, 08:30 PM

As promised, here is a pictorial How To for using a size M or size N (for our purpose, they are equal) DC power jack as a 901 fitting for battery mods.

I got my parts at Radio Shack - part number 274-1583. I have read around the forum that Maplin's has them in the UK.

Here is a pic of the part before I did anything.

The prong at the top of the photo is going to be the positive (+) contact - red wire goes here.

I used pliers to bend the unnecessary prongs back and forth until they broke off. Here is the after pic.

I removed the nut and lockwasher as this space is where I make my negative connection.

Next, I solder on my two wires. The red, or positive (+) is pretty straightforward - just connect red wire to the only remaining solder prong.
Here is a pic of that connection.

For the black, negative (-) connection, I thread my wire through a small gap in the aluminum outer shell, then solder it to the bottom of the threaded portion. Here are a few pics of this to try and make it more clear.

Only permitted 5 pics to a post, so a second post is necessary.

Here is a pic of the DC Jack attached to a 901 atomizer.

Here is link to the thread where I would prefer all discussion to go.
Possible Solution to 901 fitting to avoid battery destruction

Please do not post discussion in this thread. I am hoping to keep it easily accessible to those who are just seeing this a year or two from now.

Nice Nico ,
I did Mine Slightly differently .
As the jack has 3 prongs , I kept 2 of them .

1 prong goes to the centre pole , which we need , the other two are a broken circuit to the thread , now we only need one connection to the thread so I soldered a little solder bridge from the ' coller' of the jack to the sprung contact , this made continuity to one of the prongs. I Just broke of the redundant one and was left with 2.

ApO.

BTW : The ones that Maplins stock have a shorter centre pole which may not make contact with the centre contact on the atomizer. It looks alot shorter than the Radio-shack ones that i have used. the maplins one i have here does not make contact as the centre pole is to short. The only way around that is to trim the thread down a little.

Thanks for the tip Apostle. I always simply soldered my negative connection to the "collar" but I like the bridging idea even better. I'll try that on my next mod.

Hi Nicowolf
Thanks for all your informative postings.
I have made a couple of pen style box mods for myself.
I have been using radio shack Item: 2740252
Description: Panel-Mount Jack for my atomizer connection. The threads are perfect but it is a pain to use. I have to grind it down to just the bolt to make it work.
Do you know of a better part for pen styles?
